Freezer burn意思

Freezer burn is a term used to describe the dehydration and discoloration of food that has been stored in a freezer for an extended period of time. It occurs when the surface of the food is exposed to the cold, dry air inside the freezer, which causes the moisture in the food to evaporate. This evaporation can lead to a leathery texture, toughness, and an off-flavor in the affected areas of the food.

The signs of freezer burn include:

• Discoloration: The surface of the food may become whitish, gray, or brown.
• Texture change: The affected areas may become tough, dry, or leathery.
• Flavor change: The food may develop an off-flavor or taste.

Freezer burn does not make the food unsafe to eat, but it can affect the quality and taste of the food. To prevent freezer burn, it is important to wrap food tightly in freezer-safe packaging, leaving as little air space as possible. Additionally, it is a good practice to label and date the food when you put it in the freezer, and to use it within a reasonable amount of time to ensure the best quality.
